[gsoc2011] seam-forge plugin

Details

Description

users should have the possibility to generate codi artifacts with a seam-forge plugin. furthermore, it should be possible to refactor existing implementations.
example: it should be possible to create new xhtml pages including the corresponding type-safe page-configs for codi and a page-bean. furthermore it should be possible to move/rename existing pages easily.
the core should be independent of seam-forge - so we have the possibility to create ide-plugins which use the same logic.
